对偶对称弦的背景场方程

Background Field Equations for the Duality Symmetric String

David S. Berman, Neil B. Copland, Daniel C. Thompson

摘要:

本文描述了T-对偶对称形式中弦的背景场方程,其中目标空间的维数是双倍的,并且西格玛模型补充了约束条件。这些都是通过要求消失的双目标空间中的西格玛模型耦合的β-功能的计算。我们证明了与标准弦西格玛模型背景场方程的等价性。

英文摘要:

This paper describes the background field equations for strings in T-duality symmetric formalisms in which the dimension of target space is doubled and the sigma model supplemented with constraints. These are calculated by demanding the vanishing of the beta-functional of the sigma model couplings in the doubled target space. We demonstrate the equivalence with the background field equations of the standard string sigma model.
